I have found that it is extremely satisfying to homebrew a radio and take it out to the field and see it working. I never got that feeling from a store bought radio. I sit listening to Shortwave in the living room and glance over at my homebrew radio and smile with satisfaction.
Extremely awesome small QRPp transceiver. Received audio was extremely clean and pleasant. Congratulations and thanks for sharing this awesome home brew project.....James VA7VB
Nice work and use of your 3-D printer to make the various parts; you gave me some ideas for sure. Also, I was very surprised at the sound of the receiver. You did a great job and thanks for putting it into a video for all to see. 73...
Absolutely excellent job, such a nice sounding receiver with so few parts! And your tiny ATMega328 and si5351 board is brilliant too. No tuning, no display, half a watt and the builtin antenna tuner is well thought through. I love it! Will look at your other projects next.
Thank you for writing about my design. I had planned for the frequency to come out with Morse code in the earphone, but the software has not been written yet.
When I was a teenager, I used to love to build little projects, but never built anything beyond a crystal receiver. Your example inspires me to want to build a QRP transceiver sometime soon. KK7PQJ
A GREAT project... very well laid out into a small tin.. antenna tuner as well, thats genius thinking.. very pleasant side tone too.. well done... look forward to seeing more...
Very nicely constructed transceiver. I like the tin enclosure it looks very robust. I always enjoy your outdoor experimenting in such interesting locations. Thank you for your time in creating this video
Wonderful. I wonder what radio (s)was carried by the Norwegian Commandos who raided the heavy water plant ( Vemork) at Telemark during World War II?. I grew up watching the movie " The Heros of Telemark" as a boy in Oregon.
Awesome! Very inspirational. I love the homebrews videos and how they operate. Do you have a video, or hyperlink, about the Arduino type oscillator design?
Thanks for all your great comments on my videos. I use the SI5351 on many of my designs. It is absolutely fantastic, and it costs very little. I have some information about it on my pages: www.la6nca.net/homebrew/arduino_si5351/index.htm www.la6nca.net/homebrew/si5351/index.htm learn.adafruit.com/adafruit-si5351-clock-generator-breakout/overview
Snyggt jobbat Helge!!! Vilken fantastisk liten och välfungerande transiever. Helt otroligt verkligen. Stort grattis . Hoppas möta dig på banden någon gång. Men kanske behöver jag lära mig cw först. Hälsningar från Dalarna. 73 SA4GWT Carsten

Igjen en artg liten konstruksjon som fungerte alldeles utmerket på 60 meter. Det var sterke signaler fra deg noe som er imponerende med bare 0,2w sendereffekt. Alltid hyggelig å være han i andre enden når du tester ut dine små radioer. 73 de Asbjørn, LA5MT.
@@LA6NCA Hello Mr Helge. I have an idea on how to further simplify the circuit. We can get rid of the signal relay to the mixer. SI5351 has 2 VFOs inside. The output of VFO 1 can be directly fed to the mixer, and the output of VFO 2 can be fed to the amplifier transistors. Based on the TX signal, VFO 2 is turned on and the F-600Hz signal is supplied to the amplifier. In RX mode, VFO 2 is disabled. Your transceiver is beautiful in its simplicity! Can I place your design on various radio engineering sites and my telegraph group, with a link to your site?

Thank you for your comments.
I travel far to find the nicest places.
Very impressive. Well designed and constructed. Tx and Rex sound good.
240 km whit 0,2 watts. nice job!

Fantastic what you've done works very well on 200Mw great video.
awesome schematic and nice audio rx also tx results...73
Amazing Helge. That is impressive. Well Done. VE6KBI in Western Canada.
Congratulations, it worked very good. Thank you
Excellent project
It's an interesting scheme. I like it. Thank you.
Kjempeartig og interessant bygg av radio! Simpel men veldig god utviklet. Flott gjort!
Nice little rig in in small box. That's real QRP. Hei es 72 de PA3BYW
Enkel er den, flott arbeid. "Dead bug" konstruksjon er også et alternativ her.
Mr. Helge could you tell me the what is the C.I. for amp and AF filter? Thanks for share.
What do you mean by C.I. ?
@@LA6NCA sorry, I.C. Integrate Circuit (im from mexico and my english are awful). The Integrate circuit for make a AF amp and filter?. Thanks.
very nice project, thank you 73!

Tack.
Jag kör både AM och DSB.
Och SSB. Så vi kanske kan ha en QSO.
Thanks for sharing, 73 👍👍👍
Can you post the primary and secondary turns of the preselector/tuner please?
Great Work! Any details about that oscillator?

Takk for det fine svaret. Så flott at du bor på et sted med lite støy.
Imponerende utført ! : Kunne tenkt, å kjøpt en kopi av deg hilsen John/LA6REA
Awesome, no tubes . :D
Kjempebra! Hilsen fra W6CMY
Good day mr.Helge. Is it possible to get a transceiver control sketch so that you can experiment on other bands? 73, R1CAU/QRP
Here is a website where I have posted the program.

@@Alex_R1CAUExcellent suggestion Alex, I agree with you, a beautiful design so minimal, it makes some of my 'simple CW transceivers' look clumsy! 😂

helt utrulig å se hva du får til, er veldig imponert over folk som bygger radio selv. Ikke dårlig.
